Function
Heimeier Thermolux K thermostatic
valves are autonomously operating
temperature controllers which do not
require any electric power supply or
connection or any other kind of exter-
nal energy. They serve to control the
individual room temperature and,
thus, save energy. The Heimeier ther-
mostatic valves allow different tempe-
rature settings which can be marked
or temperature ranges be limited or
settings be blocked respectively.
Heimeier Thermolux K-thermostatic
valves consist of the thermostatic
head  and the thermostatic valve
body . If temperature rises e.g. due
to insolation, electric appliances or
people in the room, the liquid in the
temperature sensor will expand.
The corrugated tube will be com-
pressed and so throttles the water
supply to the radiator by means of the
valve spindle in the valve seat .
Should the room temperature drop
the described procedure will be re-
versed. Therefore, the thermostatic
head only needs actuation in order to
change the individual setting of the
room temperature.

Dear Customer!
You dispose now of the Thermolux K
thermostatic valve which is a product
of highest quality made by Germany’s
leading manufacturer of heating
valves.
The Heimeier Thermolux K thermosta-
tic valves are CEN certified and were
tested according to DIN EN 215. They
offer you, on the pre-condition of a
correct usage, a maximum of comfort
and energy saving.
This user information intends to make
you acquainted with the operation
and useful application of the ther-
mostatic valves. Even if you know
already well the operation and hand-
ling, you still should read these
instructions carefully and please keep
this booklet in a safe place and pass
it on to any possible later user.
For easier reference and orientation
please consult the coloured sub-
divisons of the table of contents.
Should you look for some specific
item, please refer to page 15 contai-
ning a list of headwords.
The mounting of the thermostatic
valve should exclusively be carried
out by a qualified installer (please see
Mounting Instructions on page 4).
Your installer will help you if you wish
to block an individual temperature
setting or to limit the temperature set-
ting range internally, i.e. unchangeable
from outside, either to a higher or to
a lower temperature level of your ther-
mostatic valves.
Interesting accessories are offered on
page 13.
Special features
This thermostatic head offers several
distinctive features for energy savings
and uncomplicated operation:
– The most important temperature
settings are shown in an abridged
form as INFO on the thermostatic
head
– Economy clips, blue and red
– Reduced night performance
– Temperature setting aid on the front
side
– Anti-frost protection setting
Cleaning
The thermostatic head should only be
cleaned with the upholstery brush of a
vacuum cleaner or in case of heavier
soiling, use lukewarm water containing
a mild domestic cleaning agent.
Maintenance and Service
In principle Heimeier’s thermostatic
valves do not require any maintenan-
ce at all.
In case of questions or possible
disturbances (see pages 10 and 11)
please apply to your installer (see
reverse page of this brochure) or
contact Heimeier directly.
Easier operation for visually handi-
capped persons
With a view to achieving an easier
temperature setting, the thermostatic
head disposes of perceptible mar-
kings for the basic setting (please see
page 7).
Important Notes

incorrect
The thermostatic head with incorporated
sensor must not be fitted in a vertical
position.
Mounting instructions
Incorporated sensor, remote sensor
The thermostatic valve with incorpora-
ted sensor must not be mounted in
such a way that the valve will be
covered with any curtains, radiator
covers or panelling etc., or be fitted in
narrow alcoves or even be mounted in
vertical position as in such cases no
precise temperature control will be
possible. Otherwise a remote sensor
or remote dial will be indispensable.
correct
The remote sensor can capture the
room temperature without any obstacle.
correct
The air of the room can circulate around the
thermostatic head without any obstacle.
incorrect
The thermostatic head with incorporated
sensor must not be covered with curtains.

Note
All Heimeier thermostatic heads are
duly adjusted in a climatic chamber
without any external influences like
heat accumulation, insolation etc.
Depending upon the mounting or
operating conditions, the desired
temperature can, in isolated cases,
only be achieved after having set a
deviating temperature. But this, of
course, has neither any influence on
the regulating accuracy nor on energy
saving. As a rule heating systems are
usually so designed that excessive
temperatures (Index figures 4 and 5)
will not be reached in most cases.
This, the more so, is applicable to
weather-controlled supply temperatu-
res or to the heat generator respec-
tively.
Remote dial
When mounting an underfloor con-
vector (radiator mounted underfloor),
or if the thermostatic head is covered
with furniture or any similar item, a
remote dial should be installed. The
latter captures the room temperature
without any obstacle and offers a
comfortable operation for the purpose
of setting the temperature.

Temperature Setting
Every desired room temperature can
be set by simply turning the thermo-
static head ( = colder, = war-
mer). In this case, the setting arrow
must point at the relevant setting
position (index figure, graduation line,
symbol). Intermediate adjustments are
possible. The temperature difference
from index figure to index figure is
about 4°C, and from graduation line
to graduation line about 1°C. Recom-
mended by us is a temperature set-
ting of the index figure 3 with the sun
symbol, and this represents the basic
setting of about 20°C. With a view
to saving energy a temperature
setting above index figure 4 should be
avoided, provided that already a lower
temperature setting will be sufficient
for comfortableness. It should espe-
cially be noted that only 1°C of a
lower temperature saves approx. 6%
of the heating cost.
Reduced night performance
In the evening, the thermostatic head
should be turned to the right to reach
the moon symbol, or, when using
the blue economy clip as a limitation,
to this limit stop. Experience proved
that the -setting will be fully suffi-
cient. In the morning the thermostatic
head must simply be turned to the left
in order to reach the desired tempera-
ture setting position or, when the red
economy clip will be used as a limi-
tation, to this limit stop. Even during a
longer absence a temperature re-
duction is advised to be effected.
Anti-frost protection setting
In case of a longer absence in winter,
the anti-frost position warrants that
the temperature in the rooms will not
drop below 6°C, provided, however,
the heating system is in operation and,
thus, the rooms will be protected from
frost damage. This said anti-frost pro-
tection setting can also be chosen for
rooms unused during the winter period.
Front side setting aid
The front side of the thermostatic
head serves as temperature setting
aid in case of bad vision on the cir-
cumferential printing or as setting ori-
entation from a larger distance. The
settings of the markings left and right
to the correspond to 16°C or 24°C
respectively.
Setting aid for visually handicapped
persons
If the thermostatic head is turned
in such a way that the perceptible
markings are opposite to the setting
arrow, a temperature setting of
ca. 20°C will be reached. Starting
from this said basic setting by feeling
and counting the grooves and by
correspondingly turning the ther-
mostatic head to the desired setting
position, the desired temperature
setting position can be reached
whenever the relevant groove will be
opposite to the setting arrow.
The distance between each groove in
the thermostatic head is about 1°C.

Economy clips
The thermostatic head will be
supplied, factory preset, with two
economy clips. These economy clips
are at first mounted to the right and to
the left of the short information.
These clips allow a variable
– marking,
– limiting or
– blocking
of an optimal temperature setting.
Marking of a temperature
setting (without limitation)
Upper marking
of the temperature range
For this purpose pull back the red
economy clip with your thumb up to
the stop (please see fig.1), then lift
and remove the economy clip (please
see fig. 2). Thus, the thermostatic
head can be turned and set to the
desired temperature, e.g. index figure
3 = 20°C. Thereafter, the red eco-
nomy clip must be inserted in the
groove to the right of the index figure
3 (please see fig. 3), then push the
clip forward and afterwards pull it
back to the stop with your thumb.
Lower marking
of the temperature range
For this purpose the blue economy
clip must be pulled back up to the
stop with your thumb, then lift and
remove the clip. The thermostatic
head can now be turned to the desi-
red temperature, e.g. moon
symbol = 14°C. Thereafter, the blue
economy clip is to be inserted in the
groove to the left of the moon symbol
(please see fig. 4), push the clip for-
ward and pull it back with your thumb
up to the stop.
Fig. 2: lift and remove the economy clip
Fig. 1: pull back the economy clip

Removing the limitation
For this purpose, the corresponding
economy clip must be pulled back up
to the stop with your thumb. Any
desired temperature setting can now
be made.
Blocking of a
temperature setting
For blocking a temperature setting
both economy clips must be pulled
back (please see fig. 1), the clips must
be lifted and removed (please see
fig. 2).
The thermostatic head must now be
turned to the desired temperature set-
ting, e.g. index-figure 3 = 20°C. Then
the red economy clip is to be inser-
ted in the groove right of the index
figure 3 (please see fig. 5) and be
pushed forward up to the stop. The-
reafter the blue economy clip must
be inserted in the groove left of the
index figure 3 (please see fig.5) and
be pushed up to the stop. The ther-
mostatic head cannot be deregulated
in any direction.
Removing of the blocking.
For this purpose the red and the blue
or, if need be, both economy clips
must be pulled back up to the stop.
Any desired temperature setting will
now be possible again.
Limiting of a Temperature
Setting
Upper limiting
of the temperature range
In this case the red economy clip
must be pulled back up to the stop
(please see fig. 1), lift and remove it
(please see fig. 2). Then the ther-
mostatic head can be turned to the
desired temperature, e.g. index
figure 3 = 20°C. Afterwards the
red economy clip must be inserted in
the groove right to the index figure 3
(please see fig. 3) and the clip pushed
forward up to the stop.
Now every temperature setting up to
the index figure 3 will be possible
when turning the thermostatic head.
Any temperature setting above the
index figure 3 will be impossible.
Lower marking
of the temperature range
For this purpose the blue economy
clip must be pulled back with your
thumb up to the stop, lift and remove
the clip. The thermostatic head can
now be turned and set to the desired
temperature, e.g. moon symbol=14°C.
Thereafter, the blue economy clip
must be inserted left to the moon
symbol (please see fig.4) and the clip
be pushed forward up to the stop.
Now any temperature setting can only
be made up to the moon symbol by
turning the thermostatic head. Tempe-
rature settings which are below the
moon symbol can only be made after
removing the said limitation.

For this product, the main part of the
temperature sensing liquid is situated
in the remote sensor, contrary to the
Thermolux K with built-in-sensor, and
actuates from there via the capillary
tube the corrugated tube in the ther-
mostatic head.
But otherwise the functional principle
is equal to the Thermolux K ther-
mostatic valve with built-in sensor
(please see page 2). Even the ope-
ration and the outfit are identical

Accessories
With E-Pro achieving substantial
energy savings is child’s play.
E-Pro enables an automatic reduction
of roomtemperature up to 4 °C,
without time-consuming programming
– and can be done by anyone at any
time.
Perfect for rooms that are only used
at times or in different ways, such as
bathroom, kitchen, living room or
bedroom.
In principle E-Pro has two buttons
which are used to carry out individual
time programming practically in pas-
sing. In this case a simple push of the
button replaces the typical situation of
turning the thermostatic valve down
or up.
E-Pro is the modern partner of the
HEIMEIER thermostatic valve –
regardless whether it is already on
hand or for a new installation. Energy
savings of up to 20 percent – this
cannot be done any more easily or
inexpensively!
For further information regarding
E-Pro please approach Heimeier
directly – or contact your installer
(see reverse page of this brochure).

Useful comments
Correct venting
Venting should not be used to control
the room temperature but only to
exchange stagnant air for oxygen-rich
air. Venting should be short but inten-
sive, i.e. windows should be fully
opened for a short time. But during
such venting the thermostatic head
should be turned back to the anti-
frost protection position.
After venting the previous temperature
setting can easily be found again
when using the economy clips (mar-
king, limitation).
Saving by using cost-free
external heat
Such external heat sources are e.g.
lamps, insolation, electric appliances,
people staying in the room etc.
This external heat has an influence on
the room temperature and, in turn, on
the thermostatic valve (please see
page 2).
Should the so generated heat in the
room lead to a higher room tempera-
ture than the temperature setting on
the thermostatic head, the thermosta-
tic valve will shut off the hot water
supply to the radiator and the radiator
will cool off.
